Y SPECIFICATION forming part ofr Letters Patent No. 762,896, dated June 21, 1904.

Application led March 18, 1904. Serial No. 198,790. (No model.)

T0 au w/wm t may concern:

' Be itknown that I, OSCAR FRoTsoi-IER, a citi- Zen of the United States of America, and a resident of Philadelphia, in the county of Philadel phia, in the State of Pennsylvania, have invented certain new and useful Improvements in Vindo'ws, of which the following is a speci- Iication.

, This invention relates to improvements in windows of the character shown in my Patent No. 749,608 granted January 12,- 1904, in which the sashes are arranged so that they may be rotated on horizontally-arranged pivots, as well as to slide vertically in the usual manner.

Inmy present invention I am enabled to dispense with the sash-slides shown in my aforesaid patent, and I also use a parting-bead of verysimilar construction which engages both sashes and is the sole means of preventing and permitting their rotary movement.

My invention consists .in its rpreferable embodiment in theA peculiar construction andarrangement and combinations of parts herein` after more particularly described and then definitely claimed at the end hereof. Y

In the accompanying drawings, which represent what I now consider the preferable way of carrying out my invention, but to which my claims are not necessarily limited, Figure 1.is a perspective view of a window, showing my parting-bead in the position which permits the sashes to be swung on their horizontal pivots. Fig. 2 is a sectional View showing one side of the frame, the parting-bead being shown in its inactive position in full lines. Fig. 3 represents a horizontal section of Fig. 1. Fig. 4 represents a sectional view,

on a much-enlarged scale, of the arrangement for locking the parting-bead in its active and inactive positions. Fig. 5 shows a face View of the same structure shown in Fig. 4. Fig. 6 is a perspective detail. Figs. 7, 8, and 9 are views showing diiferent forms of the parting-bead.

Referring now to the details of the drawings by numerals, 1 represents a frame which-may be formed in any desirable manner, although I show it of sheet-metal construction in Fig. 3, and within this frame is secured the sashes 2,

which may be of any preferred construction, except that I 'prefer to form' in any way whatever openings or grooves 3 and 4, which run longitudinally of the sashes, as very clearly seen in Fig. 1. As illustrated in Figs. 3 and 6, the metal forming the window-frame terminates in two inwardly-projecting parts 6 and 7, which leave a groove or opening bctween them runnin'g the full length of the frame on the inner side thereof. On each side of the part 6 and 7 is also formed a groove or opening, which I have numbered 8 and 9 and within which are contained the pivots 10 and 11. (ShownV in dotted lines.) The large opening contained within the windowframe at the rear of 8 and V9 isdesigned to contain the sash-weights. (Not shown.) As nothing new is claimed inthe frame itself nor in the pivots for the sashes,` it is believed these parts need no further description. Within the longitudinal opening or groove formed between the parts 6 and7 and which opening or groove has been described as extending the full length of thewindow-frame I insert a partingbead of novel structure, and in one of its embodiments-this parting-bead is formed of one piece of sheetv metal formed into the shape shown in section in Fig. 3 and in perspectiv'ein Fig. 6. In other werds, it comprises two vertical members 12 and 13, which iit closely against the inturned portion 6 and 7 of the frame. These members 12 and 13 are merelythe continuations ofA what may best be described as a W-shaped parting-head. the portions 14 and 15 of Awhich are shaped to fit into the longitudinal grooves 3 and 4-o`f the sashes as such grooves are showin-in Figs. 1 and 3. W'hile- I do not limit my invention to the shape of this parting-'bead` it will be noticed in my drawings that the ends of the members 12 and 13 are bent on themselves to form the deep grooves into which the portions 6 and 7 snugly fit. Whenthe parts are in their active position, this will be found to make an exceedingly tight window, as will be seen from an inspection of Fig. 3.

From an inspection of Fig. 2 it will be seen that my parting-bead is suspended from its upper end and that its lower end is free to move in and out. This may be accomplished IOO in any desired way; but at present I prefer the simple manner of hanging the partingbead on a pivot comprising an ordinary bolt 17, which passes through said bead and also throughl the vertical walls 6 and 7 of the frame 1. (See the perspective detail Fig. 6.) When the parting-bead is in a truly vertical or perpendicular position, its members 14 and 15 closely fit within the grooves 3 and 4 of the sashes, and thus the sashes may be moved vertically, but will be prevented from any rotary movement, owing to the fact that the partingbead projects into said grooves; but owing to the peculiar construction of the parting-bead it is possible to swing its forward end rearwardly on its pivot, as shown in Fig. 2. When this is done, the sashes, if first moved to the lower portion of the frame, may be swung on their horizontal' pivots, as shown in Fig. 1. Of course it will be obvious that in order to make it absolutely sure that when moved to its inactive position the lower half of the parting-bead will not project beyond the horizontal dotted line iu Fig. 2 the said parting-bead must be moved rearwardly twice as far as it normally projects. Of course it will be understood that whenever the partingbead is withdrawn to at least twice the amount that it projects it will be free from touching the sashes for the whole of its lower half. While any desired means may be used to hold this parting-bead in its active and inactive positions, I much prefer the arrangement shown in my drawings, which may be described as follows: At the extreme lower end of the parting-bead I secure avU-shaped keeper- 21, and this keeper is secured by soldering, brazing, or by the screws 22. Within the keeper is loosely supported a bolt 24, having a recess 25 in its front side, which is directly opposite a recess 26, cut into the face of the parting-bead. Secured to the window-sill inside of the frame 1 is a plate 28, provided with two openings 29 and 30, the rst of which is elongated for the purpose of adjustment and the other is adapted to receive the lower end 27 of the bolt 24, as clearly seen in Fig. 4. A screw 31 is inserted through the elongated opening 29 for the purpose of securing the plate 28 in its proper position. In order to operate the said bolt 24, a tool of the proper construction is provided to `project through the opening 24 in the parting-bead, the end of such a tool being shown in Fig. 4. However, as my invention does not reside in the tool further description thereof is unnecessary, and it will be sufficient to state that when it is desired to move the parting-bead into its inactive position the tool is inserted through the opening 26 in the parting-bead and into the opening 25 in the bolt 24. The tool may then be used to lift the bolt slightly upward, so as to free the lower end 27 from the opening 30 in the plate 28, when the operator may by pressing on the tool shove the end of the parting-bead back into the window-frame, as clearly seen in full lines in. Fig. 2 and in dotted lines in Fig. 4, when the bolt may be permitted to drop so that its end 27 projects behind the plate 28, and thus locks the partingbead in its inactive position. It will be understood that the entire lower half of the parting-bead is now entirely within the frame, and therefore as it does not contact at all with the lower sash said lower sash may be swung on its pivot. It is of course likewise to be understood that if the upper sash is slid to a lower position, so as to be below the point where the parting-bead projects from the frame, said upper sash may also be swung on its pivots.

Whenever it is desired to again lock the sashes from rotation, all that is necessary to do after the sashes have been brought into their proper vertical positionsis to insert the hooked end of the tool through the partingbead into the recess in the bolt 24, when said bolt may be lifted, as before described, and the parting-bead may then be drawn forward until the lower end 27 of the bolt is again in line with the opening 30, when said bolt is permitted to drop until it is in the position shown in full lines in Fig. 4.

In Figs. 7, 8, and 9 Ihave shown other forms of parting-beads, which in some respects are to be preferred to the form shown in Figs. 1 to 6, in that they form extremely effective weather-strips in addition to acting as parting-beads. In the form shown in Fig. 7 the parts may be just like those shown in Fig. 3, except that there is a space 22 left between the sashes, and the metal forming the weath erv strip is formed into a double portion 24, which passes into the space 22, and thus forms an effective weather-strip. As heretofore mentioned, this parting-bead is otherwise just like the one shown in Fig. 3 and is suspended from above and its lower end is allowed to swing inward. In the form shown in Fig. 8 I provide an arrangement just like that shown in Fig. 7, except that the rear end of the parting-bead is formed so as to be closed by a U- shaped or channel strip 27. In Fig. 9 the parting-bead is constructed like the form shown in Fig. 7 so far as the part 24 is concerned; butin this form the rear ends of the parting-bead are formed with portions 29,
